Abstract
Provided is a humidity conditioning method that enables absorption and desorption of moisture with low power consumption. The humidity conditioning method includes: an adjustment step of adjusting a moisture amount of hygroscopic liquid; and a measurement step of measuring concentration of a hygroscopic substance contained in the hygroscopic liquid, in which at the adjustment step, at least either moisture absorption processing of causing moisture contained in air to be absorbed by the hygroscopic liquid or regeneration processing of separating the moisture from the hygroscopic liquid is performed, the regeneration processing includes atomization processing of irradiating at least a part of the hygroscopic liquid with an ultrasonic wave to generate an atomized droplet from the hygroscopic liquid and perform removal, the atomized droplet contains a first droplet and a second droplet whose particle size is larger than a particle size of the first droplet, a concentration region of the hygroscopic substance relative to total mass of the hygroscopic liquid includes a first concentration region in which the first droplet is generated, and a second concentration region in which the secon…
